Cumulation of High-current Electron Beams: Theory and Experiment

A drastic cumulation of current density caused by electrostatic repulsion in relativistic vacuum diodes with ring-type cathodes is described theoretically and confirmed experimentally. The distinctive feature of the suggested cumulation mechanism over the conventional one, which relies on focusing a high-current beam by its own magnetic field, is a very low energy spread of electrons in the region of maximal current density that stems from a laminar flow profile of the charged-particle beam.

Study of the generation intensity in the backward wave oscillator with a ''grid'' diffraction grating as a function of the grating length

Experimental studies of the backward wave oscillator with a ''grid'' diffraction grating that is formed by a periodic set of metallic threads inside a rectangular waveguide are proceeded with study of the generation intensity as a function of the grating length.

First observation of generation in the backward wave oscillator with a "grid" diffraction grating and lasing of the volume FEL with a "grid" volume resonator

First observation of generation in the backward wave oscillator with a "grid" diffraction grating and lasing of the volume FEL with a "grid" volume resonator that is formed by a perodic set of metallic threads inside a rectangular waveguide is considered.
